Numbers can be figured, counting the angles of different shapes. For example, triangle corresponds to 3, quadrangle, or tetragon, corresponds to 4, etc. There are no one-angled or two-angled shapes, however, if the sides are curved, there is a way to obtain them, as shown on the painting.
It might seen to be an abstract painting, but it is not. Various semi-transparent colourful glass-like polygons corresponding to the numbers from 1 to 9 are placed to form 3x3 magic square matrix. The logic of colour sequence more or less follows the chromatic wheel: one-angle shape is red, two-angle is orange, triangle is yellow etc.
The sums of the “angle” numbers counted up by verticals, horizontals and diagonals of the magic square of “polygon” matrix 3x3 are equal to 15.
